FILLING-REPLENISHING LOOM.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed August 7, 1919. Serial No. 315,964.

To all whom it may concern:

Be it known that- I, EDWARD S. Srnrrsox, a citizen of the Ynited States, and a resident of Hopedale, in the county of'VVorcester and State of Massachusetts, have invented an Improvement in.Filling-Replenishing Looms, of, which the following description, in connection with the accompanying drawings, is aspecification. like characters on the drawings representing like parts.

, This invention relates to filling replenishing looms and more particularly to means for preventing breakage or injury to parts when, on'call for replenishment of filling, a filling carrier is improperly positioned for transfer.

In looms of the filling replenishing type wherein a fresh supply of filling is automatically transferred from a magazine or hopper to the shuttle when the supply of filling in the shuttle has become exhausted, it is now the common practice to provide means for actuating the transferrer only upon call for filling replenishment. In one wellknown type of filling replenishing loom, the hopper is of the rotary character and is adapted to hold a series of filling carriers, such as bobbins, which are brought successively into transferring position by rotary movement of the hopper following each call for filling replenishment. In this type of loomthe principal duty of theweaver is to keep the hopper supplied with filling carriers. In placing the" filling carriers in the rotary hopper, the weaver disengages the hopper actuating and holding mpans from the hopper, and rotates the hopper by hand as he or she places the filling carriers with a fresh supply of filling thereon in the hopper. During this time the loom continues in operation, there usually being still a number of filling carriers in the hopper ready for transfer.

when the weaver has finished his task of supplying the hopper with filling carriers, he or she may leave the'hopper with a filling ving drawings which illustrate a good, I

tical form of the 1nvent1on, and then the novel features and combinations will be decarrier improperly positioned for transfer but yet in the path of the transferrer. Under these conditions should a call for replenishment of filling occur, the transferrer will be operated, but the filling carrier being not in proper position for transfer, yet

i the path of the transferrer, breakage or injury to some of the parts is liable to occur.

An important feature of the present invention, therefore, consists in means for alternatively rotating the hopper to carry an improperly positioned filling carrier from the path of the transferrer or prevent operation of the transferrer upon call for-filling replenishment when the filling carrier is not properly positioned for transfer in the path of the transferrer. As a good practical form of the present invention with respect to the feature referred to, the holding means for the lay upon call for filling replenishment,

of the transferrer.

Other features of the invention and novel combinations of parts will hereinafter be described in connection with the accompanypracfined by the claims.

In the drawings: i Figure 1 is a perspective View of a portion of a filling replenishing loom at the replenishing side, showing more particularly the hopper and associated parts;

Fig. 2 is a vertical transverse section through the hopper and lay showing the position assumed by the parts when a filling carrier is improperly presented-for transfer n the path of the transferrer;

"Fig. 3 is a view-similar to that of Fig. 2 showing the parts in the position assumed when the hopper is given its backward rotary movement to carryan improperly positioned filling carrier out of the path of the transferrer.

The loom frame 1 maybe of usual form and suitable character for supporting the operating parts. Secured tothe loom frame is a bracket 2 from which risesthe stationary head 3 of the'rotary hopper which is mounted for rotary movement on a shaft 4- carried by the head.

Mounted in the suitable supporting portion 5 of the bracket 2 is the stud or arm 6 on which is mounted the transferrer 7 normally maintained in its upward or inoperative position by means, such as a spring 8, or other suitable means. Extending downwardly from the hub portion 9 of the transferrer is an arm 10 to which is pivotally con.-

nected at 11 the swinging dog orfinger. 12 to which is connected a pin 13 extending into the slotted portion 14 of an arm 15 carried at 16 by a part Of the usual shuttle feeler, commonly used in this type ofloom, the construction being such that upon call for replenishment of filling the slotted arm 5 is moved clockwise, viewing Figs. 2 and 3, to

' permit the dog or finger 12 to move upi Fig. 3 into the path of a hunter 17 carried r Fig. 3, which results upon call for filling rewardly from the position in'Fig. 2 to that of by the layv 18. As the lay moves forward, with the parts in position as indicated in plen'ishment, the hunter 17 strikes the l notched end portion 19 of the dog or finger 21, and by further frontward movement 7 causes the transferrer to be operated to transfer a filling carrier 20 from the hopper to the shuttle beneath. The parts'so far deq scribed are of usual construction in this type of filling'replenishing loom and being well understood by those skilled in the art, further detailed showing or description of this these heads, as usual,-have means for holding portion of the mechanism, is unnecessary.

The rotary hopper consists of the heads 21. and 22 secured upon a sleeve 23 rotatably mounted upon the shaft or support 4, and

the ends of the filling carriers or bobbins 20, as indicated in Fig. 1.

1. Secured to the rotary hopper is a toothed disk 24 by which, through the means. presently to be described, a hopper is'given its rotary movement-clockwise, viewing Figs. 2 and 3, toplace a filling carr er in transfer- .ring' position. Rotary movement 'of the hopper after transfer of a filling carrier may be: effected by variously contrived means,

- but in the present instance of theinvention the transferrer 7 has 'pivotally mounted thereonat 25 an actuator 26 carryingatooth 27*, which, as the transferrer moves downwardly during its transfer movement, clicks over the teeth of the toothed disk 24, and on upward movement of the transferrer causes rotary movement'of the hopper to present another filling carrier 20 to t-ransferring position.

carries a holding pawl 31', which, by on gagement between the teeth of the disk,

locks or holds the rotary hopper-fromgrm tary movement and with a filling carrierin proper transferring position bearing against the abutment 27. The parts thus far de-' scribed may be of usual character well understood by those skilled in the' art, and, as

"more fully explained in the patent to Ed-.

ward S. Stimp son No. 664,790, dated December 25, 1900. 4 When the weaver desiresvto place filling When a filling carrier is in transferring carriers in the rotary hopper,-'he usually disengages the a'ctuator 26 and the holding pawl 31 from engagement with the toothed disk, thereby freeing the hopper to manual rotation. During the time the weaver is fill ing the hopper with filling carriers, the loom continues to run, and if, during. this period -there should be a call for replenishment of filling effected by the usual filling detecting mechanism, it is desirable thataetuation of the replenishing mechanism'be prevented.

This is particularly true with, respect-to the so-called feeler looms whereina call for' a change offillin is announced prior to the complete exhaustion of the filling in the shuttle, so that even thougha call for filling replenishment may be made while the hopper is being filled, it is desirable that. the old filling still in the shuttle shall continue to lay its length in the shed, without the production of imperfect 'cloth and until-the weaver can manually turn the hopper to pre- It happens at times also-Ithat'when the weaver. has completed his task and released the actuating member 26' 'a11d the holding" member 31, a fillingcarrierwill not be'properly positioned for transfer that is, the weaver may release the actuating-and holding means when a filling earrier'is in -the p0,

appear that while the filling carrierfisnot in proper transferring position, it, is yet in the pathof movement :of'the transferrer, consequently, should filling; replenishment be attempted .to beieffected Iatthis time, the transferrer would'not be'able to transfer the sent a filling carrier to transferring-position.

- sition, as indicated in Fig. 2, wherein it will engages a pin 37 extending viewed in Fig. 2,

improperly positioned filling carrier and break. ge or injury of some of the parts is liable to ensue.

The present invention contemplates means for preventing such improper action. and resulting injuries, either by preventing the tran'sferrer from belt-1g operated, or by moving the rotary hopper to carry the improp erly placed filling carrier out of the path of movement of the-.transferrer. The holding means or pawl carrier 29 has a downwardly extending portion 32 which is connected to a detent 33, the lower end portion 3% of which is adapted to be engaged by the dog or finger 12, as the latter is moved upwardly to operative position. The detent 33, in the present instance of the; invention, is pivotally mounted at 35 to a fixed part of the loom, such as the bracket 2, and its upwardly extending bifurcated end 36 from the portion 32 of the holding pawl carrier 29. Should the detent 33 be moved contraclockwise, as

the latter moves upwardly into operative position, the upper end or holding pawl 31 of the carrier 29 will be moved inwardly.

Should the weaver, upon finishing his task I of filling the rotaryhopper with filling carriers, release the parts so that they assume the position indicated in Fig. 2, with'the holding tooth 31 resting upon the inclined portion 38 of a tooth of-the toothed disk, then such movement of the detent by the dog or finger will move the holding pawl 31 into or toward the bottom of the space between the teeth of the toothed disk and, perforce, cause rotation of the toothed disk andconnected rotary hopper backwardly, to thereby remove the improperly positioned filling carrier 20 from the path of movement of the-transferrer. This condition is illustrated in Fig. 2 and the resulting condition of movement of the detent 33 by the dog orxfinger 12 is indicated in Fig. 3 and where it will be seen, as indicated by the arrow, the rotary hopper has been moved backwardly to carry the misplaced filling carrier 20 out of the path of movement of the transferrer. The conditions above described are probably of most frequent occurrence, but it may sometimes happen that the holding pawl 31 may engage a tooth of the toothed disk 24 on the opposite slant of the tooth, in

which case the inward movement of the holding pawl will effect movement ofthe rotary hopper to position the improperly positioned filling carrierand bring it firmly against the abutment 27. In either case,-

- it is formed in two parts adjustably secured by thedog or finger 12, as

- a The detent 33 may be variously contrived to perform its descrlbed function, but in the present instance of the invention, and 1n order to ada t it to various conditions of use,

together by a bolt 39, this construction beingbest illustrated in Fig. 1.

The dog or finger 12 may be variously contrived to cooperate with the end 34 of the detent 33, but in the present instance of '80 the invention the upper surface portion of the dog 12 is provided with a shoulder40 which, as the dog or finger 12 is moved into operative position, as indicated in Fig. 3, engagesthe end 34: "of the detent- 33 and, causesmovement of the detent contraclock wise, viewing Fig. 2, should the holding pawl be not properly engaged with a holding tooth on the toothed disk 24. If, however, movement of the holding pawl 31 into full engagement with the recess between the teeth is prevented, as by the pawl 31 engaging the end of a tooth on the disk, then the end 34: of the detent 33, by engagement with the upper surface of the dog or finger 12,

will arrest or stop the upward movement of the dog or finger before it reaches operative position and, perforce, prevent operation of the tra'nsferrer.

From the construction described it will appear that should a call for filling replenushment occur during-the time tlie attendant' is manually restraining the holding pawl from engagement with the teeth of the ratchet disk, the detent 33-will prevent move ment of the dog or finger 12 to operative position and. thereby suspend or prevent operation of the transferrer untilsuch time as the weaver may place a filling carrier in proper transferring position by rotation of the hopper. Also, should the weaver release the holding pawl so that it does not fill in between the teeth of the ratchet disk, then upon call for'filling replenishment, the detent will be actuated by the dogor-finger 12 and cause rotation of the hopper, either 1 to move a filling carrier away from transferring position" and out of the path of the transferrer, or, as may sometimes happen, into transferring position forthe action of 1-29 the transferrer. In any event, improper and injurious operation of the parts is prevented.
